The Change Auditor Coordinator does not start due to the error "The computer is not in a site" (4255429)

When trying to start the Change Auditor Coordinator, usually after a fresh install, it fails.  The Change Auditor Coordinator log displays the error message "The computer is not in a site"

The server isn't registered in a site.

The following command can be run to confirm this, where SERVERNAME is the name of the server where the Coordinator is installed on:

nltest /server:SERVERNAME /dsgetsite

You can also check the following registry key:

HKLM\System\CurrentControlSet\Services\Netlogon\Parameters

There should be a value called either "SiteName" or "DefaultSiteName". 

Quest Support suggests that customers speak to their networking team to identify why it isn't properly joined to a site, and confirming the subnet for the server is assigned to a site in AD. Please see the following for more information:
